Title: Circuit arrangements for controlling automatic ignition devices
IPC: F23N5/20
Filed: 1975-04-03
Abstract: 1477800 Ignition circuit control LGZ LANDIS and GYR ZUG AG 3 April 1975 [11 April 1974] 13753/75 Heading F4T [Also in Division G3] A circuit for controlling an automatic igniter 13 Fig. 1, for liquid or gaseous fuels, for ensuring a complete programme cycle even in the event of temporary interruptions in supply voltage, comprises a flame monitory relay FR, an operating relay MR, a timer TZ, which is based on the change in physical parameter, and contacts tz 1 , tz 2 , which are influenced by the timer, wherein there is provided a blocking means HR, which comes into operation when there is an interruption in the programme cycle, and which triggers a fresh burner start only in dependence on the condition of timer TZ. In operation, the bimetal of TZ closes switch tz 2  and when contacts of thermostat 3 are closed, current passes to neutral line 2 via elements 1, 3, tz s , and HR, the latter being actuated to close contacts hr 1 , hr 2 , so that a blower 7 and a flame monitor 8 are connected to voltage. If there is no extraneous light present, igniter 13 and timer heater TZ 1  are connected to voltage by line 6. After a short time, contact tz 2  in circuit HR opens, which circuit remains energized due to a parallel circuit with a closed switch hr 1 . After expiry of the pre-scavenge time, timer TZ actuates switch tz 1  and a further circuit from line 6 to line 2 via elements fr 1 , tz 1 , 17, diode 19, two windings, 21, 22, of MR fr 3 , and timer heater TZ 11  or resistor 24. MR is actuated to operate switches mr 1 , mr 2 , to connect valve MV 1  to voltage, and supply fuel. MR is held by switch mr 1 , the fuel is ignited, FR is actuated to operate switches fr 1 , fr 2 , fr 3 , which cuts out ignition, cuts out heated winding TZ 1 , and disconnects winding TZ 11  respectively. MR is now held by winding 22 and resistor 24 and the bimetal of TZ cools. After expiry of post-ignition time, change-over switch tz 1  switches back to apply voltage to valve MV 11  so that a required greater heating output is released. If no flame is produced, windings TZ 1 , TZ 11 , which are arranged on the same bimetal, would have actuated safety switch tz s  to cut off the circuits. If during normal starting at any moment there is a temporary interruption in mains voltage HR will switch out the current to the igniter 13 by contact hr 2  and when the voltage returns, HR can only be actuated again when timer TZ is at its starting position. In a modification Fig. 2, safety switch tz s  is connected directly to line 6, the contact hr 2  of which lies in the MR circuit, and an additional contact hr 3  is connected between mr 1  and TZ 1 . In a further modification Fig. 3, hr 2  of HR is arranged after fr 1 . In another modification Fig. 4, a thermistor PTC replaces contact tz 2  and is connected to TZ 1 . The thermal timer TZ may be replaced by heating one or two permanent magnets up to the Curie temperature with consequencer triggering of a switching operation.

Abstract: 653,690. Controlling change-speed gearing. CLEVELAND, F. G. (Bendix Westinghouse Automotive Air Brake Co.). May 25, 1948, No. 14150. [Class 80(ii)] In a change-speed gear for motor-vehicles affording five forward speeds and reverse wherein a shifter arm 8 is turned angularly by a double-acting fluid-pressure motor 15 to engage one of three shift rails and is moved bodily by a similar motor 5, arranged at right-angles to the motor 15, to move the engaged rail so as to establish the desired gear, control is effected by a manual lever 46 moving in a gate 47 so as to operate any one of six valves 40 ... 45 controlling the supply of pressure fluid to both motors from a pipe 60, supply to the motor 5 being additionally controlled by six valves 114, 115, 116, 137, 138, 139 operated by cams 103,104 on the piston rod 13 of the motor 15, so as to ensure that, on moving the lever 46 from one speed position to another, the motor 5 cannot be energized to establish the new speed until the motor 15 has moved the arm 8 into engagement with the appropriate shift rail for the new speed. The pistons 6, 14 of the two motors are normally maintained in mid position by their springs. The two cams 103, 104, each controlling three valves, are located in separate chambers 94, 95. The valves 40... 45 are spring loaded so that, with lever 46 in neutral position as shown, the motors are vented and the arm 8 occupies the neutral position shown. If lever 46 is moved to position R (or 1), valve 43 (or 40) is operated so that pressure fluid passes via pipe 55 (or 52), double check valve 150. and pipe 153 to the righthand side of piston 14 so that the arm 8 turns to engage the right-hand shift rail. At the completion of the leftward movement of the piston 14, the cam 104 (or 103) opens the valve 139 (or 116) to allow pressure fluid to pass from pipe 55 (or 52) via pipe 149 (or 130), chamber 95 (or 94) and pipe 102 (or 101) to the right-hand (or lefthand) side of piston 6 whereby arm 8 is moved to the left (or right) to establish reverse (or first) gear. Movement of lever 46 into position 2 (or 3) from neutral, in which latter position the arm 8 already engages the middle shift rail and the cams 103, 104 hold the valves 115, 138 open, operates valve 44 (or 41) to put the right-hand (or left-hand) side of piston 6 in communication with pipe 60 via pipe 56 (or 53), and valve 138 (or 115), chamber 95 (or 94) and pipe 102 (or 101) so as to establish second or third gear. Similarly, movement of lever 46 into position 4 (or 5) operates valve 45 (or 42) so that presure fluid passes via pipe 57 (or 54), double check valve 154 and pipe 155 to the left-hand side of piston 14 whereby the arm 8 is turned to engage the left-hand shift rail. On completion of the rightward movement of piston 14, cam 104 (or 103) opens valve 137 (or 114) to allow pressure fluid to pass from pipe 57 (or 54) via pipe 147 (or 128), chamber 95 (or 94) and pipe 102 (or 101) to the right-hand (or left-hand) side of piston 6 so as to establish fourth (or fifth) gear.

Abstract: 475,425. Blasting - cartridges ; rotary rock drills. SULLIVAN MACHINERY CO. May 22, 1936, No. 14494. Convention date, July 30, 1935. [Class 9 (i)] [Also in Group XXII] A drill stem 28, Figs. 1 and 2, is provided with means adapted to release suddenly air or gas under pressure to break down the material into which the drill has penetrated. As shown, a chamber 53 is formed in the drill stem and is supplied with compressed air by central tubes 54, 73 from a compressor 70. The tube 54 opens into a small space 56 between the drill head and a valve piston 60. When the compressed air comes from the compressor, the piston is pressed on a seat 58 and closes an outlet 65, and the compressed air leaks between the piston and the tube 54 into the chamber 53. When the drilling operation is completed and the chamber 53 charged ready for operation, the compressed air supply is cut off and the tube 73 vented to atmosphere in any suitable manner, for example by means of a three-way valve. The sudden reduction of pressure in the space 56 causes the piston to move away from its seat and to uncover the outlet 65, through which the compressed air in the chamber 53 is discharged to break the material down. The drill stem is provided with external vanes 30, which convey the cuttings out of the drill hole ; and a guard plate 50 having an opening for the drill stem is provided to protect the operator from the flying of broken material during the operation. The Specification as open to inspection under Sect. 91, describes also the construction of the drilling apparatus : this apparatus is supported and propelled by tractor treads 6, Fig. 6 (Cancelled), and comprises . a base frame 5 with a pillar 7 fitting like a piston in a cylinder 8, on which a frame 16 carrying the drill stem 28 is swivelled about a horizontal axis by means of a trunnion 15. The cylinder 8 can be raised and lowered by controlling a hydraulic supply thereto and can be fastened by a clamp 21 controlled hydraulically. Similarly, the drill frame 16 can be swivelled by means of hydraulic cylinders 17, and fastened by an hydraulically controlled clamp 27. The hydraulic supply comes from a pump 10 driven by a motor 11 and is controlled by valves 19. The drill stem 28 is frictionally engaged by rollers 36, Fig. 3 (Cancelled), mounted on a shaft 34 connected by worm gearing 33 to a driving motor 31. The mountings include universal joints in yokes 42, which can be adjusted by a lever 49 to set the rollers at right-angles to the drill stem and shaft 34 to transmit rotation only of the stem, or to set the rollers at an inclination one way or the other to cause the stem to be fed longitudinally in or out while being rotated. This subject-matter does not appear in the Specification as accepted.

Abstract: 752,702. Spray carburetters. CLERK, E. J. May 19, 1954 [July 11, 1956] No. 14707/54. Class 7(3) In a carburetter having an induction passage of invariable effective cross-sectional area and controllable jet means to supply liquid fuel to the induction passage in response to the flow of air through the passage, ejector means are associated with the jet to provide adequate suction to maintain the supply of fuel therefrom when the speed of flow of air in the induction passage due to engine suction is low. In Figs. 1 and 2 the fuel supply is controlled by means of a needle valve 27 movable by a pedal or other driver operated control member. A return spring (not shown) may be provided. Compressed air supplied by a tube 43 has an ejector action on the fuel in the jet tube 23. The air is supplied only when the flow of air inspired by the engine is insufficient to draw fuel from the jet tube 23. A valve controlling the supply of compressed air may be operated in response to the rate of air flow so that the valve is open only when the speed of air flow in the choke tube is below a predetermined limit. At starting the valve 27 is set so that the fuel supply is a maximum. The jet tube 23 may be at or upstream of the throat of the choke tube. Figs. 4 and 5 show a modification in which the fuel supply is controlled by a metering pin 2 located above the fuel level. The method of assembling this embodiment is described. An upstanding rounded lip 77 is provided on the upstream side of the tip of the jet 61.
